Jets CB Darrelle Revis cleared for contact

FLORHAM PARK, N.J. (AP) -- Darrelle Revis is back in action for the New York Jets.

The All-Pro cornerback was cleared Thursday for contact in practice for the first time since suffering a concussion in the team's season opener.

Coach Rex Ryan was optimistic about Revis' chances of playing Sunday against the Dolphins in Miami, but is leaning on the team's doctors before saying the cornerback will definitely be on the field.

''If it's not the final hurdle, I don't want to be saying something that isn't true,'' Ryan said. ''Hopefully he'll play, but I guess we'll see.''

Revis was expected to practice fully Thursday after passing all required tests. He needed to be cleared by the team physician and an independent neurologist to participate in contact drills. Revis was injured Sept. 9 against Buffalo when he was accidentally kicked in the head by teammate Bart Scott while attempting a tackle.

He'll be re-evaluated after practice Thursday and Friday, but barring a setback, Revis will be back in the Jets' secondary on Sunday.

''I think you feel good when you have the best player on the field,'' Ryan said. ''That can't hurt you. ... There's only one Darrelle Revis. I know I feel great about it. It's hard not to smile. You feel great as a playcaller.''

Revis didn't travel with the Steelers for the game in Pittsburgh after not being cleared for contact late last week. He said he felt as though he were in ''a fog'' right after he was injured, but progressively felt better.

Tight end Dustin Keller (right hamstring) and safety Eric Smith (hip/knee) were upgraded Thursday to limited after not practicing Wednesday.
